Caltrans has closed Highway 101 in both directions at Richardson Grove, following a collision that occurred about an hour ago.  California Highway Patrol dispatch logs from that time note that the crash involved a bicyclist, but it was unclear whether any vehicles were involved before those logs went dark. An ambulance had been dispatched.

KMUD News reports on Facebook that someone was killed in the crash.

There is no estimated time of reopening the highway. If there is still a STOP sign in the map above at the time you read this, the highway’s still closed.

We will update when we know more.
